I'll have another thorough look at the code and I'm make sure I'm
setting up the audio channel correctly. If I still can't figure out
where I'm going wrong I'll get back to the list.
By other context I mean: I require some of the functionality of the
sequence grabber, audio channel and associated audio settings panel.
However, I need that panel in my own window. So I've moved the
settings interface items to a custom view and pointed the
SGAudioSettings at those interface items. Then, rather than showing
the window to change the settings, I grab the view and add it to the
window I already have available.
Doing this, I've done away with a number of settings that I don't
need, ie the input's physical format, output format, effects. As I've
made my modifications, I've tried to ensure that I use the default
values wherever the user would have made a selection. What I was
wondering is if maybe I've done away with a setting that is crucial
to the functioning of the audio channel and the sequence grabber, and
then naturally, if the crash report might give a hint as to what that
setting would be.
Hi Phil,
There's not enough information here. It's likely the "using some
code ... in another context" part that has the greatest bearing on
the current crash. I've not seen this crash log in any app that
uses Sequence Grabber. So you'll probably need to share code (feel
free to do this by way of a formal bug report at
bugreport.apple.com). If we can't reproduce it, we can't fix it
(or tell you how to fix your code).
Thanks.

Hi all,
I am attempting to use some of the code provided by wackedtv in
another context. I only require the audio portion, and I've
integrated the elements from the whackedtv example that I need.
However, every once in a while apparently at random, upon starting
up the recording I come across a crash (report clipping follows).
This occurs only when I begin recording, never during or when
ending the recording. Any ideas? Notes: I initialized my objects
just as whakedtv does, playthru is disabled, the audio output
device is set to built-in audio.
